1) Can anyone confirm that the iTrack Solo records at 24 bit on iPad in Auria?
The website says: 'some apps also allow 24 bit recording with the itrack Solo'
A bit vague to whether it does or not. I contacted Focusrite but no reply yet.

2) Also can anyone recommend a usb powered hub for the Scarlett 2i2? Does any powered hub work?

3) Has the 2i4 been proven to work with Auria?

any help in confirming the above would be great,
cheers

I am using the "Belkin 2.0 4-port USB white" hub with the 2i2. Works great.
